noob help on simple program

ive just started learning c++, im still in high school so i dont do it constantly, and im using the bloodshed compiler. I wrote this program and its not working quite as i had hoped. Here is the code.

Code:

---

#include <iostream>

using namespace std;

int main()
{
    cout<<"Enter Password: ";
    string password;
    cin >> password;
    getline(cin, password ,'\n');
    if (password=="lala") {
        cout<<"Access Granted";
        _sleep ( 3000 );
        }
    else {
        cout<<"Access Denied\n";
        _sleep(1000);
        cout<<"Closing Program\n";
        _sleep(1000);
        }
}

---

when running the program it will ask you for a password and when u enter "lala" the correct password it says access denied, then closing program, then it closes as if it was wrong. I looked over the code plenty of times and cant quite figure out the problem. pls help.

I'd rather you put those brackets at the same level as the ifs. Makes it easier to read.
And what's the probem? Have you considered why you first use cin to read password and then later use getline to read into the same variable once again?

Code:

---

    cin >> password;
    getline(cin, password ,'\n');

---

This is wrong, and I'll explain why.

Input to your program is buffered. When you type in your password, it might look like this:

Code:

---

'l', 'a', 'l', 'a', '\n'....

---

The first line you have will read until it hits '\n' in this case. Reading strings with cin, however, means that the '\n' char is left in the input buffer. That means the input buffer will look like this:

Code:

---

'\n'

---

getline() comes around and tries to read now. It reads into the same location you had cin read to. It reads this as an empty string and the output buffer is now empty because getline(), unlike cin, will eat up the '\n' char and discard it.

Your variable password is now an empty string, not "lala".

Solution: Get rid of the first line.

thank you for the help that solved my problem. Thanks for the explanation that makes a lot more sense. Really quick to that was only like 10 mins from my original post.
